Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
Pyrimidines have one ring structure in their molecular composition. This ring is composed of six atoms, including four carbon atoms and two nitrogen atoms, arranged in a hexagonal shape.
Purines because purines have two rings where as pyrimidines have only one ring.
Thymine is a single-ringed nitrogenous base.
Pyrimidines (cytosine, thymine, uracil) have a single-ring structure, while purines (adenine, guanine) have a double-ring structure. Purines always pair with pyrimidines in DNA and RNA bases. Additionally, purines are larger molecules compared to pyrimidines.
Thymine and cytosine are two nitrogen bases found in DNA. DNA is composed of thousands of nucleotides which are composed of one of four nitrogen bases. Both of these nitrogen bases are also pyrimidines, or they have one ring like structure See related link for more info on thymine, cytosine and pyrimidines.

Pyrimidines have a single ring in their molecule.
Purines and pyrimidines are the building blocks of nucleic acids. The difference between purines and pyrimidines is in the number of carbon-rings present. Pyrimidines contain one carbon-ring while purines have two.
Pyrimidines have one ring structure in their molecular composition. This ring is composed of six atoms, including four carbon atoms and two nitrogen atoms, arranged in a hexagonal shape.
Purines because purines have two rings where as pyrimidines have only one ring.
These rings are known as pyrimidines.
The large bases that have two carbon-nitrogen rings are called purines.
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
Thymine is a single-ringed nitrogenous base.
Cytosine, uracil and thymine are the three pyrimidines.
Various medications and dietary supplements contains pyrimidines. Pyrimidines are important components to HIV therapeutics, the thiamine vitamin, and the narcotic barbitone.
There are three resonance structures of pyrimidines. These structures involve the delocalization of electrons within the aromatic ring of the molecule, leading to different arrangements of double bonds.
